Random Stats

Zachary Hahn was bored one day, and so he put together his copy of Halo and a Timex stopwatch and calculated a bunch of statistics about the various speeds of things in Halo.
Most averages were calculated from 10 or 15 samples, and there was some rounding done here at HBO to conform with significant digit rules. A multiplayer mode with "Kill in Order" turned on with nav points provided the distance from head to head.
If nothing else, you must admire the obscene attention to detail.

[1] The odd distance is due to the fact that the distance between the driver and the front of the Warthog is 3.6 meters. Head to head was 100 m, but one head was 3.6 meters behind the front grill.
[2] According to Charles Gough, the man responsible for the Warthog's behavior, on flat ground and with no air friction, the Warthog can do a bit over 52 mph.
[3] The body driving the Ghost is 2.1 meters behind the nose of the vehicle.
[4] Like the Warthog, the Tank driver sits back from the front of the vehicle - in this case, 5.3 meters.
